Device for measuring current

Abstract

A device for measuring current is connected to a data processing apparatus loaded with a current value comparison program for performing a quality test on a portable electronic apparatus with a battery. The portable electronic apparatus has a battery compartment for receiving the battery. The device for measuring current includes: a power supplying module for generating a low-voltage current; a dummy battery with a shape of the battery for inserting into the battery compartment, the dummy battery electrically connected to the power supplying module and the portable electronic apparatus to provide the low-voltage current generated by the power supply module to the portable electronic apparatus, forming a power supply loop to the portable electronic apparatus; and a current measuring module electrically connected to the power supply loop for measuring a current value of the power supply loop when the portable electronic apparatus is performing a specific function and transmitting the measured current value to the data processing apparatus for comparison. The present invention does not heavily rely on manual operations to measure the current of the portable electronic apparatus.

Description

FIELD OF THE INVENTION[0001]The present invention relates to devices for measuring current, and more particularly, to a device for measuring current of a portable electronic apparatus with a built-in battery.BACKGROUND OF THE INVENTION[0002]Generally, manufacturers of electronic devices perform a series of tests on their products before shipping or mass production in order to provide consumers with good-quality products. Among them, one of the tests determines whether current consumptions of a portable electronic apparatus (e.g. a palm computer or smart phone) under different operating conditions are all within their ideal ranges, so as to detect any faulty products at an earlier stage.[0003]Specifically, testing personnel connects a portable electronic apparatus to be tested to an external power supply, and connects a digital multimeter to the power supply. Then, the power supply is operated to provide a low voltage to the portable electronic apparatus, and the portable electronic ...

Benefits of technology

[0006]Another objective of the present invention is to provide a device for measuring current that allows the testing personnel to obtain a more accurate test result.

[0011]Therefore, the present invention allows the testing personnel to perform a current measuring procedure on the portable electronic apparatus through simple and convenient steps, which eliminates the shortcoming of the prior art in which a significant amount of manual work is required. Thus, a more accurate test result can be obtained. Further, the overall yield of the portable electronic apparatus is efficiently improved, thus reducing the production cost of the manufacturer is reduced.

Problems solved by technology

However, steps involved in such a current testing procedure are complicated and trivial.

There is a concern that the connectors might fall off during the test.

In addition, manual testing and determination are required, thus reducing testing efficiency.
